Ok here i go, i currently have a Switch with firmware 8.1.0 and Atmosphere. It's been a while and in the past i never update or downgraded. I want to go to 9.0.1 so i can play Animal Crossing New Horizons but i don't actually know how to update the switch from 8.1.0 to 9.0.1 and how to use a newer version of Atmosphere to load it up again.
So i found this video
right here on how to install custom firmware of 9.01 but he's talking about when its brand new. I already have 8.1 and games installed on my switch so its different in my case.
I'm confused on what steps to take first. Do i need to delete everything from my SD card and then find out how to manually update from 8.1 to 9.0.1 (offline) first and after that follow the tutorial above so i treat it as if its brand new on 9.0.1? Or is there an easier way to update from 8.1 to 9.0.1 offline and have the correct atmosphere for the newer version?
Hopefully someone can help me! Thanks in advance.
